Product details

Integrator's spec recap — 5SQ2670-0KA06

The breaking capacity is 3 kA per both EN 60898 and IEC 60947-2, which sets the maximum fault current it can safely interrupt at 400 V AC, 50 Hz. Overvoltage category 3 and energy limiting class 3 place it for fixed-installation use in distribution boards where coordination with upstream devices is expected.

Form, fit, and function — panel integration

The 4-pole (3P+N) footprint matches the same cutout as a 4-pole MCB, but the neutral pole is switched, not just solid-linked — verify your panel's neutral busbar scheme if you are replacing a 4P device with a solid neutral.

Frequently asked questions

What is the closest functional alternate to 5SQ2670-0KA06?

The closest functional alternate within the same SENTRON 5SQ family is the 5SQ2670-0KA15, which shares the same 4-pole (3P+N) configuration, C-curve, 3 kA breaking capacity, 400 V AC rating, and 55 mm depth — the only difference is the rated current: 15 A versus 6 A. It is a drop-in replacement for the same panel footprint and wiring scheme, provided the load current is within the 15 A rating.

Will 5SQ2670-0KA06 drop into a panel specified around 5SQ2670-0KA15 without rewiring?

Yes, form, fit, and function are identical between the two — same 3 width units, same 55 mm depth, same 3P+N wiring scheme. The only difference is the 6 A rating on this part versus 15 A on the 5SQ2670-0KA15. No rewiring is needed, but verify the load current does not exceed 6 A.

What compliance documentation does SENTRON provide for 5SQ2670-0KA06?

The part is rated per EN 60898 and IEC 60947-2 for breaking capacity, and carries overvoltage category 3 and energy limiting class 3 designations. Standard SENTRON documentation includes CE declaration of conformity; specific RoHS/REACH/UL documentation should be confirmed at quote time as it may vary by production batch.

How do I get current pricing and availability for 5SQ2670-0KA06?

Submit an RFQ through the storefront. The part is sourced to order through independent distribution; availability and current pricing are confirmed at quote time.
